MUOS will offer 10 times greater communications capacity to the mobile warfighter over the Navy's current generation of Ultra High Frequency Follow-On spacecraft to relay narrowband tactical information such as voice calls, data messaging, file transfers and email on rates of up to 384 Kilobits per second. From its eventual spot in geosynchronous orbit, matching Earth's rotation to hover in a parking spot 22,300 miles (35,888 km) up, the expansive footprint of MUOS 1 will cover a huge swath of the planet to serve ships, submarines, aircraft, land vehicles and terminals in the hands of troops.
